<script runat="server">
sub Page_Load
if Not Page.IsPostBack then
dim mycountries=New DataSet
mycountries.ReadXml(MapPath("countries.xml"))
rb.DataSource=mycountries
rb.DataValueField="value"
rb.DataTextField="text"
rb.DataBind()
end if
end sub
sub displayMessage(s as Object,e As EventArgs)
lbl1.text="You selected: " & rb.SelectedItem.Text
end sub
</script>
<form runat="server">
<asp:RadioButtonList id="rb" AutoPostBack="True"
runat="server" onSelectedIndexChanged="displayMessage" />
<asp:label id="lbl1" runat="server" />
</form>
<script runat="server">
sub Page_Load
if Not Page.IsPostBack then
dim mycountries=New DataSet
mycountries.ReadXml(MapPath("countries.xml"))
rb.DataSource=mycountries
rb.DataValueField="value"
rb.DataTextField="text"
rb.DataBind()
end if
end sub
sub displayMessage(s as Object,e As EventArgs)
lbl1.text="You selected: " & rb.SelectedItem.Text
